Description

TECHNICAL FIELD

[0001] This document relates to a system and method for vehicle battery charge maintenance in a storage facility.BACKGROUND

[0002] Storage facilities for recreational vehicles (RVs), boats, motorcycles, and seasonal-use automobiles provide owners with secure locations to store their vehicles for extended periods, particularly during off-seasons when they are not in use. These facilities serve a crucial function by ensuring that vehicles remain protected from the elements, theft, and other environmental factors. However, one of the most common and persistent challenges faced by both vehicle owners and facility managers is battery depletion. Prolonged storage without regular use can cause vehicle batteries to lose their charge, preventing the vehicle from starting when the owner is ready to use it again. In addition to causing inconvenience and delays, this depletion can also lead to reduced battery lifespan, as deep discharges over extended periods are known to accelerate the wear and deterioration of battery cells. As a result, vehicle owners are often required to replace batteries more frequently, which can lead to unexpected and costly maintenance expenses.

[0003] In an effort to mitigate these issues, many vehicle owners attempt to use the electrical outlets provided by the storage facility to maintain their vehicle's battery charge. They may connect various charging devices, including battery maintainers, conventional chargers, or inverters, which provide a continuous trickle charge to prevent the battery from depleting entirely. Unfortunately, this practice can introduce a series of new problems. One of the primary risks arises from improper use of the facility's electrical outlets and infrastructure. Vehicle owners may plug in high-current-draw appliances, such as space heaters, refrigerators, power tools, or air conditioning units, which can place excessive strain on the facility's electrical system. This overload can exceed the system's intended capacity, potentially causing circuit breakers to trip or even leading to a complete electrical failure in the storage facility. In the case of RVs, the owner may attempt to power the entire vehicle and its onboard systems, such as lights, appliances, and climate control, using the storage facility's electrical supply. This further amplifies the strain on the facility's power grid, as the high energy demand can lead to overheating of circuits, increased risk of fire hazards, and damage to both the vehicle and the facility's electrical infrastructure. In addition, even when the vehicle owner only plugs in a conventional charger or trickle charger, there is a risk of damage to the facility. This occurs because conventional chargers must be matched to the type of battery. For example, if the charger is designed for charging a lead-acid battery, but the battery being charged is a lithium ion battery, the battery may catch fire or explode. Some chargers include multiple settings for different types of batteries, but these chargers must be manually set to the correct mode, and thus still increase risk.

[0004] In conventional storage facilities, a single circuit is typically used by several vehicles within a designated storage area. While this arrangement might seem efficient, it introduces several critical problems, particularly when the circuit is overloaded or tripped. When multiple vehicle owners connect their vehicles to the same electrical circuit, the total power draw from all connected devices can quickly exceed the circuit's designed capacity. For example, if several vehicles are charging simultaneously and each vehicle is drawing power for extra systems (such as heaters, cooling units, refrigerators, or lights), the combined current demand may surpass the capacity of the circuit. This overload causes the circuit breaker to trip as a protective measure. While tripping the breaker is intended to prevent overheating and potential fire hazards, it can also lead to a number of logistical and operational issues for both the facility owner and the vehicle owners.

[0005] The primary issue arises when a breaker trip goes unnoticed, which is common in large storage facilities with many vehicles. Since multiple users share the same circuit, when a single breaker trips, it can affect the power supply to all connected vehicles, leaving them without charging or maintenance power. Vehicle owners may not immediately realize that their battery charging system has been disrupted, especially if the tripped breaker is located in a distant or hard-to-access part of the facility. As a result, the vehicles may remain disconnected from their power sources for an extended period, leading to depleted batteries when the owners return to retrieve their vehicles. This not only defeats the purpose of keeping the vehicle's battery maintained during storage, but also compounds the issue, requiring more time and resources to remedy the problem.

[0006] In the worst-case scenario, when the circuit breaker is repeatedly tripped and owners neglect to address the issue or fail to detect it, the vehicles may suffer from prolonged battery depletion. This can result in significant inconvenience, with some owners potentially having to replace batteries or seek professional assistance to revive their vehicles. The problem can also affect multiple vehicles simultaneously when one breaker protects several storage spaces or units in a given area. In such cases, a single vehicle that is drawing excessive power or causing a fault in the circuit can inadvertently impact other vehicles on the same line. This increases the complexity of troubleshooting and resolution, as the issue may not be immediately apparent to all users who are affected. In some cases, a fault in one vehicle can cause power failures for others, compounding the inconvenience for both the facility management and the owners.

[0007] Additionally, when a circuit is tripped, the process of manually resetting the breaker can be time-consuming and sometimes overlooked. In facilities where management or staff may not be readily available to address these issues, it can lead to extended periods of downtime for all vehicles connected to the affected circuit. If multiple circuits are used to serve large numbers of vehicles, troubleshooting which circuit is at fault can also become an arduous and time-consuming process.

[0008] In conclusion, while the intent behind utilizing a storage facility's electrical system for vehicle battery maintenance is to ensure vehicle readiness, improper use of these power sources creates significant risks. These risks include overloading the electrical system, causing circuit breakers to trip, leading to undetected charging failures, and increasing the potential for battery damage or safety hazards. These risks are not easily mitigated by the facility or the users.SUMMARY

[0029] The present disclosure may be understood more readily by reference to the following detailed description taken in connection with the accompanying figures and examples, which form a part of this disclosure. It is to be understood that this disclosure is not limited to the specific materials, devices, methods, applications, conditions, or parameters described and / or shown herein, and that the terminology used herein is for the purpose of describing particular embodiments by way of example only and is not intended to be limiting of the claimed inventions.

[0030] More specifically, this disclosure, its aspects and embodiments, are not limited to the specific material types, components, methods, or other examples disclosed herein. Many additional material types, components, methods, and procedures known in the art are contemplated for use with particular implementations from this disclosure. Accordingly, for example, although particular implementations are disclosed, such implementations and implementing components may comprise any components, models, types, materials, versions, quantities, and / or the like as is known in the art for such systems and implementing components, consistent with the intended operation.

[0031] The present disclosure is related to a controlled, facility-managed charging solution that ensures proper trickle charging for stored vehicles while preventing unsafe or excessive power usage. The system disclosed herein provides regulated power distribution tailored for battery maintenance while mitigating the risks associated with unauthorized appliance use or improper charging methods.

[0032] The present disclosure addresses the challenges of battery maintenance and thus reduces electrical overload issues, minimizes fire hazards, and ensures that stored vehicles receive the appropriate level of battery maintenance without compromising safety. The devices and systems of the present disclosure are configured to leverage renewable energy sources, such as solar power, to provide continuous trickle charging, ensuring that batteries remain functional and ready for use when needed.

[0033] The present disclosure is related to a charge controller 100 that is configured to provide continuous trickle charging. As shown in FIG. 1, the charge controller 100 has a main body 104, a first electrical connector 106, and a second electrical connector 108. The first electrical connector 106 is configured to electrically couple with a solar panel 110. In some embodiments, the first electrical connector 106 is a non-standard electrical connector. This allows the charge controller 100 to be connected to an electrical source that is not available to other systems. For example, while the charge controller 100 can be connected to the electrical source, other systems like a refrigerator or an A / C unit cannot be connected because the electrical connection only works for the charge controller 100. Thus, the first electrical connector 106 may be a unique, non-standard electrical connector. The second electrical connector 108 is configured to electrically couple with a battery 112 of a vehicle. In some embodiments, different from the first electrical connector 106, the second electrical connector 108 is a standardized electrical connector. This allows the second electrical connector 108 to couple with any type of battery 112 that implements that standardized connection. In some embodiments, the second electrical connector 108 is configured to couple with alligator clips that can then be attached directly to the positive and negative terminals of the battery 112.

[0034] The main body 104 may have an indicator 118 on a surface 120 of the main body 104 that is configured to indicate to the user the status of the charge controller 100. The status of the charge controller 100 may be that the charge controller 100 is currently in a charge mode, that the charge controller 100 is currently in a maintenance mode, and / or that the charge controller 100 is running into some error. Any other status may be indicated.

[0035] In some embodiments, the charge controller 100 has built-in safety features to prevent overcharging, reverse polarity, over current, and short circuits. These features thus make it easier to use the charge controller 100 and safer for the charging environment, such as a storage facility (discussed in more detail below), and for the electrical circuit to which the charge controller 100 is connected.

[0036] The charge controller 100 may be configured to operate in a charge mode and in a maintenance mode. When in the charge mode, the charge controller 100 is configured to charge the battery 112. The battery 112 may be any type of rechargeable battery. For example, the battery 112 may be an absorbed glass mat battery (AGM), a lead-acid battery, or a lithium-ion battery. Other types of batteries may also be implemented, including wet cell, gel cell, flooded, maintenance-free, deep cycle, sealed, LiFePO4 lithium, and lithium iron batteries.

[0037] The charge controller 100 may have a unique charge profile that is uniquely suited for charging any type of battery 112 without any manual or other adjustment of any settings on the charge controller 100. In some embodiments, the charge profile is configured to charge all types of rechargeable batteries. The charge controller 100 may be configured to charge any type of battery without requiring a change in mode, setting, or charge profile. Instead, the charge profile implemented by the charge controller 100 is designed to charge any type of battery without creating a hazard to individuals or the facility. The charge controller 100 is a one-size-fits-all charger. Thus, when using the charge controller 100, there is no need for a user to press a button or otherwise manually select a charging mode, and the user does not need to worry about matching the battery to the charger like with conventional chargers. In other words, the charger's charging signal wave patterns are configured to charge each of absorbed glass mat batteries, lithium ion batteries and lead-acid batteries, in addition to others, without a change in the charger settings. In addition, the charge controller 100 may be configured to dynamically change a voltage applied to the battery 112 based on a charge level of the battery 112. For example, if the battery 112 has a lower charge level, the charge controller 100 may be configured to apply a particular voltage that is suited for charging the battery 112 at that charge level, and once the battery 112 has charged to a higher charge level, the charge controller 100 may be configured to respond by applying a different voltage that is more suited for charging the battery 112 at that higher charge level. In particular, this is helpful in implementing trickle charging, where the goal is not to charge the battery 112 as quickly as possible, but instead to maintain the battery 112 with a working charge for a long period of time. Thus, once the battery 112 reaches or approaches a full charge capacity, the charge controller 100 may be configured to apply a smaller voltage to conserve energy. The charge controller 100 may thus be configured to reduce the voltage applied to the battery 112 as the battery 112 approaches full charge capacity.

[0038] When in the maintenance mode, the charge controller 100 may be configured to monitor the charge level of the battery 112 without actively charging the battery 112. If the charge level of the battery 112 dips below a predetermined threshold, the charge controller 100 may be configured to briefly charge the battery 112 to maintain a full charge and then stop charging again.

[0039] The present disclosure is also related to a storage facility 102 that is configured for long-term vehicle storage, as shown in FIGS. 2-3. The storage facility 102 provides a particularly useful scenario for the charge controller 100 disclosed above. The storage facility 102 may comprise a plurality of storage spaces 122. Each of the plurality of storage spaces 122 may comprise an area for storage of a vehicle, such as an RV, a boat, an ATV, a car, or a motorcycle. Any vehicle with a battery 112 may be stored. The area for storage may be a portion of a parking lot, a stall, a covered parking space, a garage, a storage locker, a storage unit, or any other area for storage. In some embodiments, the area for storage is not necessarily designed for storage of a vehicle and instead may be designed for storage of other articles or items. An electrical power connection 114 may be mounted to a surface 116 bordering the area for storage such as a wall, a roof support surface, or a pole. This provides support to the electrical power connection 114 instead of leaving the electrical power connection 114 to float around and potentially get in the way or get damaged. Each of the plurality of storage spaces 122 may also comprise a solar panel 110, shown in more detail in FIG. 4. The solar panel 110 is configured to convert incident sunlight to electric potential energy and provide the electric potential energy to the electrical power connection 114 in the area for storage. The solar panel 110 may have an adjustable angle to allow the solar panel 110 to be oriented more directly towards the sun. In some embodiments, the solar panel 110 is a 30 V solar panel. The solar panel 110 thus only provides power to the storage spaces 122 when the solar panel 110 is in the sunlight. This works well for trickle charging, where power is not needed constantly. Instead, it is suitable for the charge controller 100 to receive power only during particular portions of the day and to occasionally go without power for a day or two during cloudy conditions. In some embodiments, the solar panel 110 is mounted on a roof 124 covering the storage space 122 (see FIGS. 2-3). In some embodiments, the solar panel 110 is mounted on a pole 126 or other structure configured to raise the solar panel 110 and allow the solar panel 110 to receive more incident sunlight (see FIG. 6).

[0040] Of particular note, in some embodiments, each solar panel 110 is electrically isolated from other solar panels 110 of the plurality of storage spaces 122, as can be seen in the embodiment shown in FIG. 3, where each solar panel is electrically coupled to the corresponding junction box 128 and to the light 130, but is electrically isolated from the electrical circuit and components of adjacent storage spaces 122. Similarly, each storage space 122 of the plurality of storage spaces 122 may be electrically isolated from the other storage spaces 122. This helps to protect customers of the storage facility 102 from the scenario where a breaker is tripped, interrupting the supply of electricity to multiple storage spaces 122. Thus, each plurality of storage spaces 122 may be “off-grid,” meaning that the storage space 122 and / or the solar panel 110 is not electrically connected to public utilities, to an electrical grid, or to other, adjacent solar panels 110 or storage spaces 122. By isolating each storage space 122 and solar panel 110, any problems that arise, in particular from an individual misusing the system, will only affect a single storage space 122 and solar panel 110. In particular implementations, a solar panel 110 may provide electricity to two adjacent storage spaces 122, with just the two spaces being electrically isolated from other pairs of two storage spaces 122. In one particular embodiment, a solar panel 110 may provide electricity to four adjacent storage spaces 122. As with any of these examples, solar panel 110 may also include a solar panel array, and the use of the single, solar panel 110, should be understood to mean one or more panels of any wattage.

[0041] The storage facility 102 may also comprise a plurality of charge controllers 100 described above. These charge controllers 100 may be provided by the storage facility 102 to be installed in the storage spaces 122 to provide trickle charging to the batteries 112 in each storage space 122, as shown in FIGS. 3 and 5. Thus, each of the plurality of charge controllers 100 may be configured to be installed in a storage space 122 of the plurality of storage spaces 122. In addition, each charge controller 100 may be configured to electrically couple with the solar panel 110 of the storage space 122 through the electrical power connection 114 and with the battery 112 of the vehicle in the storage space 122, as described above. Once the charge controller 100 has been installed in a storage space 122 of the plurality of storage spaces 122, the charge controller 100 is configured to work with the solar panel 110 to provide off-grid trickle charging to the battery 112 of the vehicle, as shown in FIG. 5. The solar panel 110 converts incident sunlight into electricity and provides power to the charge controller 100, which then uses this power to charge or maintain the charge on the battery 112.

[0042] In some embodiments, each storage space 122 may have a junction box 128 that is positioned in or adjacent to the storage space 122 and / or the area for storage, as shown in FIGS. 2-3. The electrical power connection 114 may be housed in the junction box 128, and thus the junction box 128 may be mounted on the surface 116. In some embodiments, the junction box 128 is protected by an electrical cover 134, such as a weather-proof cover or some other cover configured to protect the junction box 128 and / or the electrical power connection 114. The junction box 128 is electrically coupled to the solar panel 110 and is configured to electrically couple with the charge controller 100. Thus, the junction box 128 is the connection point through which the charge controller 100 is configured to electrically couple with the solar panel 110. As noted above with respect to the first electrical connector 106 of the charge controller 100, the junction box 128 may comprise a unique, non-standard electrical connector that is configured to couple with the charge controller 100, but not with other, more typical electrical connectors. This allows the storage facility 102 to control what devices can be connected to and powered by the solar panel 110 and helps to prevent misuse and thus improves the safety and security of the storage facility 102.

[0043] In some embodiments, each storage space 122 of the storage facility 102 may also comprise a light 130 with a battery 132 (see FIGS. 3 and 6). The light 130 may be positioned to illuminate the storage space 122 in which the light 130 is installed. The battery 132 may be electrically coupled to the solar panel 110 such that, when the solar panel 110 generates power, the battery 132 is charged by the solar panel 110. The light 130 may be electrically coupled to the battery 132 so that the light 130 is configured to light up using power drawn from the battery 132. In some embodiments, the light 130 is configured to light up only when an ambient light level is lower than a threshold level. This helps to preserve the charge of the battery 132 until the light 130 is needed. In addition, the light 130 may be controllable by a switch such that a user can manually turn the light 130 on and off. In some embodiments, the light 130 is operably coupled to a motion sensor and is configured to light up when motion is detected in the vicinity of the light 130. Thus, the combination of the light 130 and the battery 132 may be configured to receive power from the solar panel 110 and provide illumination to the storage space 122 as needed / desired. In other particular embodiments, the battery 132 may be used to provide stored electricity to the electrical power connection 114, such as is referenced in relation to FIGS. 2-3 above, to enable charging through the charge controller 100 when the solar panel 110 is not generating electricity, such as at night or on a cloudy day.

[0044] Many additional implementations are possible. Further implementations are within the CLAIMS.

[0045] It will be understood that implementations of the charge controller include but are not limited to the specific components disclosed herein, as virtually any components consistent with the intended operation of various charge controllers may be utilized. Accordingly, for example, it should be understood that, while the drawings and accompanying text show and describe particular charge controller implementations, any such implementation may comprise any shape, size, style, type, model, version, class, grade, measurement, concentration, material, weight, quantity, and / or the like consistent with the intended operation of charge controllers.

[0046] The concepts disclosed herein are not limited to the specific charge controllers shown herein. For example, it is specifically contemplated that the components included in particular charge controllers may be formed of any of many different types of materials or combinations that can readily be formed into shaped objects and that are consistent with the intended operation of charge controllers.

TECHNICAL FIELD

[0001] This document relates to a system and method for vehicle battery charge maintenance in a storage facility.BACKGROUND

[0002] Storage facilities for recreational vehicles (RVs), boats, motorcycles, and seasonal-use automobiles provide owners with secure locations to store their vehicles for extended periods, particularly during off-seasons when they are not in use. These facilities serve a crucial function by ensuring that vehicles remain protected from the elements, theft, and other environmental factors. However, one of the most common and persistent challenges faced by both vehicle owners and facility managers is battery depletion. Prolonged storage without regular use can cause vehicle batteries to lose their charge, preventing the vehicle from starting when the owner is ready to use it again. In addition to causing inconvenience and delays, this depletion can also lead to reduced battery lifespan, as deep discharges over extended periods are known to accelerate the wear and deterioration of battery cells. As a result, vehicle owners are often required to replace batteries more frequently, which can lead to unexpected and costly maintenance expenses.

[0003] In an effort to mitigate these issues, many vehicle owners attempt to use the electrical outlets provided by the storage facility to maintain their vehicle's battery charge. They may connect various charging devices, including battery maintainers, conventional chargers, or inverters, which provide a continuous trickle charge to prevent the battery from depleting entirely. Unfortunately, this practice can introduce a series of new problems. One of the primary risks arises from improper use of the facility's electrical outlets and infrastructure. Vehicle owners may plug in high-current-draw appliances, such as space heaters, refrigerators, power tools, or air conditioning units, which can place excessive strain on the facility's electrical system. This overload can exceed the system's intended capacity, potentially causing circuit breakers to trip or even leading to a complete electrical failure in the storage facility. In the case of RVs, the owner may attempt to power the entire vehicle and its onboard systems, such as lights, appliances, and climate control, using the storage facility's electrical supply. This further amplifies the strain on the facility's power grid, as the high energy demand can lead to overheating of circuits, increased risk of fire hazards, and damage to both the vehicle and the facility's electrical infrastructure. In addition, even when the vehicle owner only plugs in a conventional charger or trickle charger, there is a risk of damage to the facility. This occurs because conventional chargers must be matched to the type of battery. For example, if the charger is designed for charging a lead-acid battery, but the battery being charged is a lithium ion battery, the battery may catch fire or explode. Some chargers include multiple settings for different types of batteries, but these chargers must be manually set to the correct mode, and thus still increase risk.

[0004] In conventional storage facilities, a single circuit is typically used by several vehicles within a designated storage area. While this arrangement might seem efficient, it introduces several critical problems, particularly when the circuit is overloaded or tripped. When multiple vehicle owners connect their vehicles to the same electrical circuit, the total power draw from all connected devices can quickly exceed the circuit's designed capacity. For example, if several vehicles are charging simultaneously and each vehicle is drawing power for extra systems (such as heaters, cooling units, refrigerators, or lights), the combined current demand may surpass the capacity of the circuit. This overload causes the circuit breaker to trip as a protective measure. While tripping the breaker is intended to prevent overheating and potential fire hazards, it can also lead to a number of logistical and operational issues for both the facility owner and the vehicle owners.

[0005] The primary issue arises when a breaker trip goes unnoticed, which is common in large storage facilities with many vehicles. Since multiple users share the same circuit, when a single breaker trips, it can affect the power supply to all connected vehicles, leaving them without charging or maintenance power. Vehicle owners may not immediately realize that their battery charging system has been disrupted, especially if the tripped breaker is located in a distant or hard-to-access part of the facility. As a result, the vehicles may remain disconnected from their power sources for an extended period, leading to depleted batteries when the owners return to retrieve their vehicles. This not only defeats the purpose of keeping the vehicle's battery maintained during storage, but also compounds the issue, requiring more time and resources to remedy the problem.

[0006] In the worst-case scenario, when the circuit breaker is repeatedly tripped and owners neglect to address the issue or fail to detect it, the vehicles may suffer from prolonged battery depletion. This can result in significant inconvenience, with some owners potentially having to replace batteries or seek professional assistance to revive their vehicles. The problem can also affect multiple vehicles simultaneously when one breaker protects several storage spaces or units in a given area. In such cases, a single vehicle that is drawing excessive power or causing a fault in the circuit can inadvertently impact other vehicles on the same line. This increases the complexity of troubleshooting and resolution, as the issue may not be immediately apparent to all users who are affected. In some cases, a fault in one vehicle can cause power failures for others, compounding the inconvenience for both the facility management and the owners.

[0007] Additionally, when a circuit is tripped, the process of manually resetting the breaker can be time-consuming and sometimes overlooked. In facilities where management or staff may not be readily available to address these issues, it can lead to extended periods of downtime for all vehicles connected to the affected circuit. If multiple circuits are used to serve large numbers of vehicles, troubleshooting which circuit is at fault can also become an arduous and time-consuming process.

[0008] In conclusion, while the intent behind utilizing a storage facility's electrical system for vehicle battery maintenance is to ensure vehicle readiness, improper use of these power sources creates significant risks. These risks include overloading the electrical system, causing circuit breakers to trip, leading to undetected charging failures, and increasing the potential for battery damage or safety hazards. These risks are not easily mitigated by the facility or the users.SUMMARY

The specific examples below will enable the disclosure to be better understood. However, they are given merely by way of guidance and do not imply any limitation.

[0029] The present disclosure may be understood more readily by reference to the following detailed description taken in connection with the accompanying figures and examples, which form a part of this disclosure. It is to be understood that this disclosure is not limited to the specific materials, devices, methods, applications, conditions, or parameters described and / or shown herein, and that the terminology used herein is for the purpose of describing particular embodiments by way of example only and is not intended to be limiting of the claimed inventions.

Similarly, when values are expressed as approximations, by use of the antecedent “about,” it will be understood that the particular value forms another embodiment. All ranges are inclusive and combinable.

[0030] More specifically, this disclosure, its aspects and embodiments, are not limited to the specific material types, components, methods, or other examples disclosed herein. Many additional material types, components, methods, and procedures known in the art are contemplated for use with particular implementations from this disclosure. Accordingly, for example, although particular implementations are disclosed, such implementations and implementing components may comprise any components, models, types, materials, versions, quantities, and / or the like as is known in the art for such systems and implementing components, consistent with the intended operation.

[0031] The present disclosure is related to a controlled, facility-managed charging solution that ensures proper trickle charging for stored vehicles while preventing unsafe or excessive power usage. The system disclosed herein provides regulated power distribution tailored for battery maintenance while mitigating the risks associated with unauthorized appliance use or improper charging methods.

[0032] The present disclosure addresses the challenges of battery maintenance and thus reduces electrical overload issues, minimizes fire hazards, and ensures that stored vehicles receive the appropriate level of battery maintenance without compromising safety. The devices and systems of the present disclosure are configured to leverage renewable energy sources, such as solar power, to provide continuous trickle charging, ensuring that batteries remain functional and ready for use when needed.

[0033] The present disclosure is related to a charge controller 100 that is configured to provide continuous trickle charging. As shown in FIG. 1, the charge controller 100 has a main body 104, a first electrical connector 106, and a second electrical connector 108. The first electrical connector 106 is configured to electrically couple with a solar panel 110. In some embodiments, the first electrical connector 106 is a non-standard electrical connector. This allows the charge controller 100 to be connected to an electrical source that is not available to other systems. For example, while the charge controller 100 can be connected to the electrical source, other systems like a refrigerator or an A / C unit cannot be connected because the electrical connection only works for the charge controller 100. Thus, the first electrical connector 106 may be a unique, non-standard electrical connector. The second electrical connector 108 is configured to electrically couple with a battery 112 of a vehicle. In some embodiments, different from the first electrical connector 106, the second electrical connector 108 is a standardized electrical connector. This allows the second electrical connector 108 to couple with any type of battery 112 that implements that standardized connection. In some embodiments, the second electrical connector 108 is configured to couple with alligator clips that can then be attached directly to the positive and negative terminals of the battery 112.

[0034] The main body 104 may have an indicator 118 on a surface 120 of the main body 104 that is configured to indicate to the user the status of the charge controller 100. The status of the charge controller 100 may be that the charge controller 100 is currently in a charge mode, that the charge controller 100 is currently in a maintenance mode, and / or that the charge controller 100 is running into some error. Any other status may be indicated.

[0035] In some embodiments, the charge controller 100 has built-in safety features to prevent overcharging, reverse polarity, over current, and short circuits. These features thus make it easier to use the charge controller 100 and safer for the charging environment, such as a storage facility (discussed in more detail below), and for the electrical circuit to which the charge controller 100 is connected.

[0036] The charge controller 100 may be configured to operate in a charge mode and in a maintenance mode. When in the charge mode, the charge controller 100 is configured to charge the battery 112. The battery 112 may be any type of rechargeable battery. For example, the battery 112 may be an absorbed glass mat battery (AGM), a lead-acid battery, or a lithium-ion battery. Other types of batteries may also be implemented, including wet cell, gel cell, flooded, maintenance-free, deep cycle, sealed, LiFePO4 lithium, and lithium iron batteries.

[0037] The charge controller 100 may have a unique charge profile that is uniquely suited for charging any type of battery 112 without any manual or other adjustment of any settings on the charge controller 100. In some embodiments, the charge profile is configured to charge all types of rechargeable batteries. The charge controller 100 may be configured to charge any type of battery without requiring a change in mode, setting, or charge profile. Instead, the charge profile implemented by the charge controller 100 is designed to charge any type of battery without creating a hazard to individuals or the facility. The charge controller 100 is a one-size-fits-all charger. Thus, when using the charge controller 100, there is no need for a user to press a button or otherwise manually select a charging mode, and the user does not need to worry about matching the battery to the charger like with conventional chargers. In other words, the charger's charging signal wave patterns are configured to charge each of absorbed glass mat batteries, lithium ion batteries and lead-acid batteries, in addition to others, without a change in the charger settings. In addition, the charge controller 100 may be configured to dynamically change a voltage applied to the battery 112 based on a charge level of the battery 112. For example, if the battery 112 has a lower charge level, the charge controller 100 may be configured to apply a particular voltage that is suited for charging the battery 112 at that charge level, and once the battery 112 has charged to a higher charge level, the charge controller 100 may be configured to respond by applying a different voltage that is more suited for charging the battery 112 at that higher charge level. In particular, this is helpful in implementing trickle charging, where the goal is not to charge the battery 112 as quickly as possible, but instead to maintain the battery 112 with a working charge for a long period of time. Thus, once the battery 112 reaches or approaches a full charge capacity, the charge controller 100 may be configured to apply a smaller voltage to conserve energy. The charge controller 100 may thus be configured to reduce the voltage applied to the battery 112 as the battery 112 approaches full charge capacity.

[0038] When in the maintenance mode, the charge controller 100 may be configured to monitor the charge level of the battery 112 without actively charging the battery 112. If the charge level of the battery 112 dips below a predetermined threshold, the charge controller 100 may be configured to briefly charge the battery 112 to maintain a full charge and then stop charging again.

[0039] The present disclosure is also related to a storage facility 102 that is configured for long-term vehicle storage, as shown in FIGS. 2-3. The storage facility 102 provides a particularly useful scenario for the charge controller 100 disclosed above. The storage facility 102 may comprise a plurality of storage spaces 122. Each of the plurality of storage spaces 122 may comprise an area for storage of a vehicle, such as an RV, a boat, an ATV, a car, or a motorcycle. Any vehicle with a battery 112 may be stored. The area for storage may be a portion of a parking lot, a stall, a covered parking space, a garage, a storage locker, a storage unit, or any other area for storage. In some embodiments, the area for storage is not necessarily designed for storage of a vehicle and instead may be designed for storage of other articles or items. An electrical power connection 114 may be mounted to a surface 116 bordering the area for storage such as a wall, a roof support surface, or a pole. This provides support to the electrical power connection 114 instead of leaving the electrical power connection 114 to float around and potentially get in the way or get damaged. Each of the plurality of storage spaces 122 may also comprise a solar panel 110, shown in more detail in FIG. 4. The solar panel 110 is configured to convert incident sunlight to electric potential energy and provide the electric potential energy to the electrical power connection 114 in the area for storage. The solar panel 110 may have an adjustable angle to allow the solar panel 110 to be oriented more directly towards the sun. In some embodiments, the solar panel 110 is a 30 V solar panel. The solar panel 110 thus only provides power to the storage spaces 122 when the solar panel 110 is in the sunlight. This works well for trickle charging, where power is not needed constantly. Instead, it is suitable for the charge controller 100 to receive power only during particular portions of the day and to occasionally go without power for a day or two during cloudy conditions. In some embodiments, the solar panel 110 is mounted on a roof 124 covering the storage space 122 (see FIGS. 2-3). In some embodiments, the solar panel 110 is mounted on a pole 126 or other structure configured to raise the solar panel 110 and allow the solar panel 110 to receive more incident sunlight (see FIG. 6).

[0040] Of particular note, in some embodiments, each solar panel 110 is electrically isolated from other solar panels 110 of the plurality of storage spaces 122, as can be seen in the embodiment shown in FIG. 3, where each solar panel is electrically coupled to the corresponding junction box 128 and to the light 130, but is electrically isolated from the electrical circuit and components of adjacent storage spaces 122. Similarly, each storage space 122 of the plurality of storage spaces 122 may be electrically isolated from the other storage spaces 122. This helps to protect customers of the storage facility 102 from the scenario where a breaker is tripped, interrupting the supply of electricity to multiple storage spaces 122. Thus, each plurality of storage spaces 122 may be “off-grid,” meaning that the storage space 122 and / or the solar panel 110 is not electrically connected to public utilities, to an electrical grid, or to other, adjacent solar panels 110 or storage spaces 122. By isolating each storage space 122 and solar panel 110, any problems that arise, in particular from an individual misusing the system, will only affect a single storage space 122 and solar panel 110. In particular implementations, a solar panel 110 may provide electricity to two adjacent storage spaces 122, with just the two spaces being electrically isolated from other pairs of two storage spaces 122. In one particular embodiment, a solar panel 110 may provide electricity to four adjacent storage spaces 122. As with any of these examples, solar panel 110 may also include a solar panel array, and the use of the single, solar panel 110, should be understood to mean one or more panels of any wattage.

[0041] The storage facility 102 may also comprise a plurality of charge controllers 100 described above. These charge controllers 100 may be provided by the storage facility 102 to be installed in the storage spaces 122 to provide trickle charging to the batteries 112 in each storage space 122, as shown in FIGS. 3 and 5. Thus, each of the plurality of charge controllers 100 may be configured to be installed in a storage space 122 of the plurality of storage spaces 122. In addition, each charge controller 100 may be configured to electrically couple with the solar panel 110 of the storage space 122 through the electrical power connection 114 and with the battery 112 of the vehicle in the storage space 122, as described above. Once the charge controller 100 has been installed in a storage space 122 of the plurality of storage spaces 122, the charge controller 100 is configured to work with the solar panel 110 to provide off-grid trickle charging to the battery 112 of the vehicle, as shown in FIG. 5. The solar panel 110 converts incident sunlight into electricity and provides power to the charge controller 100, which then uses this power to charge or maintain the charge on the battery 112.

[0042] In some embodiments, each storage space 122 may have a junction box 128 that is positioned in or adjacent to the storage space 122 and / or the area for storage, as shown in FIGS. 2-3. The electrical power connection 114 may be housed in the junction box 128, and thus the junction box 128 may be mounted on the surface 116. In some embodiments, the junction box 128 is protected by an electrical cover 134, such as a weather-proof cover or some other cover configured to protect the junction box 128 and / or the electrical power connection 114. The junction box 128 is electrically coupled to the solar panel 110 and is configured to electrically couple with the charge controller 100. Thus, the junction box 128 is the connection point through which the charge controller 100 is configured to electrically couple with the solar panel 110. As noted above with respect to the first electrical connector 106 of the charge controller 100, the junction box 128 may comprise a unique, non-standard electrical connector that is configured to couple with the charge controller 100, but not with other, more typical electrical connectors. This allows the storage facility 102 to control what devices can be connected to and powered by the solar panel 110 and helps to prevent misuse and thus improves the safety and security of the storage facility 102.

[0043] In some embodiments, each storage space 122 of the storage facility 102 may also comprise a light 130 with a battery 132 (see FIGS. 3 and 6). The light 130 may be positioned to illuminate the storage space 122 in which the light 130 is installed. The battery 132 may be electrically coupled to the solar panel 110 such that, when the solar panel 110 generates power, the battery 132 is charged by the solar panel 110. The light 130 may be electrically coupled to the battery 132 so that the light 130 is configured to light up using power drawn from the battery 132. In some embodiments, the light 130 is configured to light up only when an ambient light level is lower than a threshold level. This helps to preserve the charge of the battery 132 until the light 130 is needed. In addition, the light 130 may be controllable by a switch such that a user can manually turn the light 130 on and off.
